Sony ICF-SW77 vs ICF-SW55 vs Tecsun PL-310ET: Radio Aparecida 11855 kHz, Brazil

Hi there, my best reception of Radio Aparecida to-date on the ICF-SW77, although I didn't realise at the time! The ICF-SW55 also performs very well, particularly on the narrow audio bandwidth filter, however, the Tecsun (understandably) struggles with this weak signal, but I think brief audio is heard once the narrowest filter has been selected. Recorded in Oxford UK on 29/12/16 at 20:29 hrs UTC using a Wellbrook ALA1530 active loop antenna. Thanks for watching.
